Today, Star Wars: The Last Jedi opens in theaters everywhere. I saw it last night. It’s very good, it’s very long, I love the porgs, and to say anything more would probably be in violation of spoiler law (for more, check out what our friends at The A.V. Club had to say). However, what I can talk about in more detail is the looming battle that should cause a more seismic rift in the galaxy: the Sweater Wars.

2 Chainz has been selling ugly “Dabbing Santa” Christmas sweaters on his webstore since December 2015, with a share of the proceeds working to benefit homeless veterans, disabled children, and arts education. It recently came to his attention that Walmart has been selling almost the exact same design to benefit, well, Walmart.

Last night, 2 Chainz posted a screenshot of the Walmart online store to Instagram with a hoodie and sweater almost identical to his dabbing Santas. “Someone please tell Walmart they didn’t get permission to use this patent or likeness in anyway,” he wrote. “We use this sweater this time of year to spread togetherness and also give back to those who are less fortunate or not able to provide for their families at the time.”

It’s becoming something of an annual tradition for high-profile rappers to feud with Walmart over trademark disputes during the holidays. Last December, Run-D.M.C. sued the company (along with Amazon, Jet.com, and some of those retailers’ business partners) for $50 million over selling and distributing merchandise bearing the group’s trademarked logo without their permission.
